Adjustment assembly for back-to-back enclosures, and back-to-back enclosure assembly employing the same

ABSTRACT

An adjustment assembly adjustably couples enclosures, such as a meter breaker panelboard and a load distribution panelboard, in a back-to-back configuration within a structure, such as a wall. The adjustment assembly includes a first end member at or about the top end of one of the enclosures, a second end member at or about the bottom end of the other enclosure, and at least one fastener coupling the end members together. A number of elongated apertures in at least one of the end members, such as slots and arcuate apertures, provide translational and pivotal adjustment, respectively. The fastener, which may comprise bolts and wingnuts to enable such adjustment without requiring separate tools, extends from one enclosure through at least one of the elongated apertures in the end member of the other enclosure in order to couple the enclosures together while enabling adjustment of one enclosure with respect to the other.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to enclosures and, moreparticularly, to enclosures which are coupled together in a back-to-backconfiguration. The invention also relates to an adjustment assembly forback-to-back enclosure assemblies.

2. Background Information

Buildings, such as for example, commercial buildings and residences,typically have an electrical distribution center with one or moreenclosures, such as for example, boxes or cabinets, which houseelectrical equipment (e.g., without limitation, relays; circuitbreakers; meters; transformers). The enclosures protect the electricalequipment. For example, when mounted on the exterior of the building,the enclosure generally shields the enclosed electrical equipment fromthe environment and, in particular, damage caused by moisture. Whetherdisposed on the interior or the exterior of the building, the enclosuretypically also includes a door or access panel, and thus serves theadditional purpose of resisting undesired access to the electricalequipment housed within the enclosure.

In certain applications, two or more enclosures are employed in aback-to-back configuration. For example, one enclosure, such as a loaddistribution panelboard, is mounted on the interior of the building withits back facing the opposite direction of the back of another enclosureto which is coupled. The other enclosure may be, for example, a meterbreaker panelboard which is accessible from the exterior of thebuilding. In other words, the load distribution panelboard and the meterbreaker panelboard are coupled together and mounted back-to-back on thesame wall of the building. The load distribution panelboard is disposedon the inside surface of the wall and the meter breaker panelboard isdisposed on the exterior of the wall. Accordingly, the two panelboards,which are normally separate devices, are joined together.

Known back-to-back enclosure designs suffer from a number ofdisadvantages, including the fact that the load distribution panelboard,which faces the interior of the building, is typically fixedly fastenedto the meter breaker panelboard, thus making it stationary and renderingit substantially incapable of being adjusted. Accordingly, once theenclosures are installed, the load distribution panelboard, which istypically mounted in a semi-flush orientation, cannot be adjusted by theinstaller as necessary to, for example, accommodate various wallboard orother substrate thicknesses, and/or other deviations or irregularities.The fit and finish of the installation can, therefore, be compromised.

Accordingly, there is room for improvement in back-to-back electricalenclosure assemblies.

For example, without limitation, two alternative plate members 168, 268are shown in FIGS. 5A and 5B. In FIG. 5A, the plate member comprises awasher 168 which includes an elongated slot 174 and a pair ofprotrusions 176 protruding upward from the substantially flat plane ofthe washer 168. The elongated slot 174 permits the aforementionedfasteners to slide with respect thereto, while the pair of protrusions176 are designed to fit within one of the slots 60, 62 (FIG. 6). It willbe appreciated, however, that any combination of an elongated slot 174,one or more protrusions 176, and a combination of elongated slots 174and protrusions 176, could be employed.

In the example of FIG. 5B, the plate member is a cam member 268 having alobe 270 and an adjustment portion 272. The adjustment portion includesa threaded fastener member 274 which is engageable by a nut such as thewing nut previously discussed, and further includes a head 276 which maybe adjusted in order to pivot the cam 268 so that lobe 270 engages, forexample, side wall 18, as shown in FIG. 6, and moves one of thepanelboards (e.g., load distribution panelboard 6) with respect to theother. Specifically, the cam 268 may be engageable, for example, by ascrewdriver (not shown) or other suitable tool (not shown) in order toeffectuate such adjustment. Once adjusted, the wing nut 78 may betightened on threaded fastener member 274, as shown in FIG. 6. The cam268 may optionally include a second protrusion 278, as shown in FIG. 5B.The second protrusion would function to engage, for example, slot 62 inorder to provide a pivot point about which cam 268 may rotate in orderto provide the aforementioned adjustment of the panelboard 6. It will beappreciated, however, that any combination of plate members 68, 70, 168,268, could be employed without departing from the scope of theinvention.

As shown in FIG. 6, the fasteners 56, 58 extend from holes 57, 59 inhood 52 through the slots 60, 62. Once the enclosure assembly 2 isadjusted and positioned, as desired, the wing nuts 76, 78 are tightenedas previously discussed, in order to initially secure the assembly 2 ina desired position. Subsequently, at least one of the panelboards (e.g.,load distribution panelboard 6) is further secured, in the desiredposition, within the wall 100. Specifically, the side walls 16, 18and/or flanges 17, 19 extending therefrom, are nailed, screwed, stapled,or otherwise suitably secured to one or more studs 102 within the wall100, as shown. In this manner, an optimized, secure installation withinthe wall 100 may be achieved.
